    Uchida hydraulic pumps, now primarily integrated under the Bosch Rexroth brand, are renowned for their high-pressure performance and durability in mobile machinery. Overview of Top Uchida Hydraulic Pump Series

    Uchida's product line is characterized by its axial piston designs, which are industry standards for excavators and heavy construction equipment. AP2D Series:

    Application: Primarily used in mini-excavators (1.5 to 5 tons).

    Features: This is a double-variable displacement piston pump with an additional gear pump. It is designed for compact spaces while maintaining high efficiency. A10V / A10VO Series: Application: General industrial and mobile hydraulics. The best technical resource is not a single

    Features: Known for medium-pressure applications, these pumps offer good suction characteristics and low noise levels. A4V Series: Application: High-pressure closed-circuit drives.

    Features: Swashplate design allows for infinitely variable flow, commonly found in travel drives for heavy machinery. Key Specifications & Performance

    Based on the standard technical documentation found in Uchida-Rexroth catalogs, these pumps share several high-end technical traits:

    Displacement Range: Varies from small 10cc units to large-scale 250cc+ models.

    Operating Pressure: Nominal pressures typically range between 250 bar (3,625 psi) and 350 bar (5,076 psi), with peak pressures reaching up to 400 bar. When searching, use specific strings like: "Uchida APP-48"

    Mounting Standards: Most utilize SAE or ISO standard mounting flanges and shafts for easy replacement and integration. Maintenance and Catalog Access

    Since Uchida was acquired by Rexroth, most "top" PDF catalogs are now hosted under the Bosch Rexroth technical documentation portal.

    Seal Kits: When searching for parts, catalogs often specify "Uchida-Rexroth" kits to ensure compatibility with older Japanese-manufactured units.

    Identification: Always check the Type Code on the pump's nameplate (e.g., AP2D25LV1RS), as this specifies the exact displacement, control device, and rotation required for a matching replacement.


    If you operate machinery from Komatsu, TCM, or Nissan Forklift (all heavy users of Uchida pumps), their technical support teams can email you the "top" internal catalogue used by their service departments.

    When you locate your "Uchida hydraulic pump catalogue pdf top", ensure it covers these core series, as these are the most common in excavators, forklifts, and press brakes:

    For those installing a new pump, the catalogue provides the maximum recommended suction velocity (usually 0.5 to 1.0 m/s for Uchida piston pumps). This prevents cavitation.
